Event-driven vs continuous monitoring
Event-driven monitoring is the commercial default. Cameras run analytics; events are streamed to the ARC for operator verification and response. Pricing is per camera per month plus event volume.
Continuous monitoring — operators watching feeds live — is reserved for very high-risk sites or short-term protected periods. Cost scales with staffed hours, not cameras.
What sites actually pay per month
Ranges below are typical UK commercial pricing for event-driven monitored CCTV. US pricing is broadly comparable in USD terms.
What's often not in the per-camera price
Bandwidth, supplementary lighting, audio challenge speakers, keyholder dispatch and out-of-hours fees are commonly invoiced separately. Ask explicitly.
Indicative monitored CCTV cost — event-driven model
Per-camera per-month UK ranges for analytics-enabled event-driven monitoring.
| Feature | Small site | Mid-sized site | Large / complex site |
|---|---|---|---|
| Cameras monitored | 4-8 | 12-32 | 40+ |
| Per-camera per-month | £12-£25 | £10-£20 | £7-£15 |
| Setup / onboarding | £200-£500 | £400-£1.2k | £1k-£3k+ |
| Bandwidth allowance | Included | Tiered | Site-specific |
| Keyholder dispatch (per event) | £35-£70 | £35-£70 | Often retained |
In summary
- Most commercial CCTV monitoring is event-driven, not continuous.
- Per-camera pricing drops with volume — larger sites pay less per stream.
- Bandwidth and dispatch are commonly extras; clarify upfront.
Frequently asked questions
Is event-driven monitoring as effective as continuous?
For most commercial sites, yes — tuned analytics surface the events that matter and operators verify them in seconds. Continuous monitoring is for very high-risk or short-term protected operations.
Are out-of-hours rates higher?
Monitoring fees usually don't change by hour. Keyholder dispatch and engineer call-out fees often do.
Why does per-camera pricing drop at higher volumes?
Alarm receiving centres price on operator load per site, not per camera. A well-tuned twelve-camera site produces only marginally more events than a well-tuned four-camera site, so the fixed operator overhead is spread more widely. Larger sites also negotiate bandwidth and analytics licensing at wholesale rates that smaller sites cannot access.
Are police response fees included in monitoring costs?
No. Police response is provided by the local force at no direct charge once verified intent is established. However, repeated false alarms can trigger response withdrawal in both the UK and US, so monitoring providers factor in the operational cost of verification tuning to protect your site's response eligibility over time.
What happens if my broadband drops during monitored hours?
Well-specified commercial CCTV monitoring uses dual-path signalling — typically broadband plus a cellular fallback — so a broadband outage triggers automatic failover within seconds. The ARC is notified of the path failure and treats the site with heightened attention until connectivity is restored. Single-path monitored CCTV is not appropriate for commercial premises.
Can I mix monitored and unmonitored cameras?
Yes. It is common practice to monitor perimeter, approach and high-value zones actively, while recording only for internal overview cameras where evidence retrieval is the primary purpose. This selective monitoring model keeps operator load — and cost — proportionate to actual risk without forcing every camera into an ARC event stream.
How much bandwidth does event-driven monitoring use?
Event-driven monitoring transmits short pre and post-event clips rather than continuous streams, so bandwidth is modest — typically ten to fifty gigabytes per camera per month on a well-tuned commercial site. Continuous cloud recording, by contrast, can push a single 4K camera past one terabyte per month, which changes the connectivity design entirely.
Is there a minimum contract length for monitored CCTV?
Most UK and US ARCs work on annual contracts with monthly billing. Twelve months is standard; some providers offer three-month rolling terms at a premium. Multi-year contracts often secure a five to ten percent discount but reduce your ability to change provider if the operational service quality drops below expectations later.
